DNA & Replication

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA, resulting in two identical DNA molecules.

Front

Where is DNA usually found in a cell?

Back

DNA is usually found in the nucleus of a cell.

Front

What is the order of DNA replication?

Back

The order of DNA replication involves unwinding the double helix, pairing new nucleotides with the original strands, and forming two new double helices.

Front

What is the relationship between DNA, chromosomes, and genes?

Back

DNA is hereditary information organized into strands called chromosomes, which contain small segments called genes that code for specific proteins.

Front

What are the three main processes involving DNA?

Back

The three main processes involving DNA are replication, transcription, and translation.

Front

What is the role of genes in DNA?

Back

Genes are segments of DNA that contain the instructions for making proteins.

Front

What is the difference between replication and transcription?

Back

Replication is the process of copying DNA, while transcription is the process of converting DNA into RNA.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do the nitrogenous bases pair in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).
